Tiny improvement request:
I have this large workflow that reads from a CSV file and spits out a detailed report. During the development of the workflow, when I run it, the Knime console shows the following message:
WARN GroupBy 1 invalid aggregation column(s) found
Unfortunately it does not tell me in which node and there is no 'yellow triangle' on any of the group-by nodes, so I need to go through each and every one of the group by nodes to find it, not a trivial task, since the workflow has several metanodes, some within other metanodes.
(I found the culprit, and removed the aggregation column.)
So if any of the developers are reading this: it would be nice if the warning message contained more information on the node it is warning about.
